Endoscopy
An endoscopy allows your doctor to look inside your oesophagus using a thin, flexible tube with a light and a camera (an endoscope). The endoscope is passed carefully down your throat towards your stomach. You will normally be given a local anaesthetic to numb your throat and you may also be given a sedative to help you relax. The procedure shouldn’t hurt but it may feel a bit uncomfortable. As well as looking inside your oesophagus, the doctor may also take small samples of tissue for analysis in the laboratory. This is called a biopsy.
Barium swallow
This involves drinking a harmless liquid called barium, which coats the lining of your oesophagus so that it shows up on an X-ray. X-rays are taken after you have swallowed the barium and these will show whether anything is blocking your oesophagus, which may indicate that you have a cancerous tumour. If oesophageal cancer is diagnosed, you will be offered further tests to assess the location and size of the tumour such as:
A CT scan – this type of scan takes a series of X-rays and puts them together to create a detailed 3D picture of the inside of your body.
A PET scan – a position emission tomography scan shows how far cancer has spread.
An endoscopic ultrasound scan – uses sound waves to create an image of your oesophagus and surrounding organs.
Laparoscopy – this is performed under general anaesthetic. It involves making a small incision in your skin and inserting a thin, flexible tube with a camera at one end to see inside your oesophagus.
